Cool! Thanks for the report! I’ve been using p83 quite a bit over the past several months, too. I love it! I have found it’s a great addition to really sex up a mix.
Wow. I usually use two sprays @ 12.5mcg per spray, so 25 total. I might double that and see what happens. 
I’ve seen almost exactly the same results as you. I’ve paired it with MX135, IS/B, and MX282 as well as a mix I made myself (based off of Tisha’s “Bewitched” mix: Vavoom: first try of my cured roll-on mix, meeting my son's friend's single dad).
I plan to try it more when paired up with p86. I tried that a bit at first, but when my To-Go of p86 ran out I never ordered it again. Have to get more of that one…
